i made
ArtHider Addon a long time ago before switching myself over to ctmod's suite of addons.
it's a simple mod that basically runs those script commands on load, no config, no options, just paste in addons dir & go. uninstall by deleting the folder
i notice you mentioned MoveAnything mod.
i would also like to suggest moving to
Visor +
VisorGUI in place of MoveAnything! MA! has been on its last leg for awhile now, fixes being cobbled together by various people in various forums, etc., while visor has been gaining popularity and support
it is an ace mod so you know it's well written and maintained -=)
using visor & visorgui you can /vzg toggle, click & hold the GRAB button over your gryphons, and Hide Frame. or if you know the frame names you can "/vz set f=framename h=TRUE" and from then on it's hidden.
i hope this helps you out!
